Question

5. Identify the domain and range of the functions below. (3 points) (A) ** Domain: y=x-3-2y = |x-31 - 2 Range: (B) Domain: Range: Elevation (4) 1000 1500 1400 1300- 1200 1100 1000 900 3 Y 5 Distance Hiker Travels (mi)

Answer 1

The domain is the set of x-values for which the function is defined for.

The range is the set of y-values for which the function is defined.

Now, looking at the graph, we see that the x-values range from

x = 0 to x = 12

And, the y-values range from

y = 1000 to y = 1500

Thus, we can say:

`\begin{gathered} \text{Domain}=\mleft\lbrace0\colon12\mright\rbrace \\ \text{Range}=\mleft\lbrace1000\colon1500\mright\rbrace \end{gathered}`
